An update to the next version is always reasonable, usually in the range of about $50 for the Elements versions and about $100 for the Pro. For example, you can buy WaveLab Elements, try it out, and upgrade to WaveLab Pro for the difference in price. Steinberg have a very clear policy regarding upgrade and update pricing whereby you basically pay the difference to the next higher edition and you are not expected to pay full price for the next version.

As a user of several ex-Sony products (though not Sound Forge), if Magix do produce a new version, be prepared for a very high “upgrade” price, effectively you are likely to be expected to re-purchase the product.
